PBMC Humanized Mouse Models
Benefits of using PBMC mice for I/O research
- Human Immune Cell Integration: PBMC models incorporate human peripheral blood mononuclear cells, allowing researchers to study interactions between human immune cells and cancer cells in a controlled in vivo environment, leading to more relevant preclinical data.
- Immune Checkpoint Inhibition Evaluation: These models are ideal for evaluating the efficacy of immune checkpoint inhibitors and other immunotherapies, providing critical insights into their mechanisms of action and potential clinical efficacy.

CD34+ Humanized Mouse Models
Benefits of using CD34+ mice for I/O research
- Long-Term Human Immune System Development: CD34+ mouse models are engrafted with human hematopoietic stem cells, leading to the development of a long-term, self-renewing human immune system. This allows for extended studies on immune response and therapy effects over time.
- Multifaceted Immuno-Oncology Research: These models support the study of a wide range of immuno-oncology treatments, including cell therapies, vaccines, and antibody-based therapies, providing a versatile platform for preclinical research.
- High Relevance to Human Hematopoiesis: CD34+ models closely mimic human hematopoiesis and immune cell differentiation, making them highly relevant for studying hematologic malignancies and evaluating hematopoietic toxicities of new immunotherapies.

GEM Humanized Immune Checkpoint Inhibitor Models
Benefits of using humanized immune checkpoint inhibitors for I/O research
- Enable the evaluation of human-specific biological therapies in vivo faster than traditional animal models
- Double KI models allow combination therapy evaluation
- Lack of expression of the murine target gene, avoiding cross-reactivity
- Provides a more predictive model for how drugs will perform in the clinic
